Hi Divya,
In twitter it looks like a standard tweet but when you post it, but then if you open that it takes the user to a mobile optimized landing page that allows for all of the same functionality that Shoppost has in Facebook. I have attached an example for you to see of the tweet and here is the link to a landing page for you to view as well: http://share.shoppost.com/08d15818-545b-e257-db29-4b035013fee8/
Feel free to contact me directly with any other questions.
